Product Description:
Fluorescent Oil dye SL3600 is a concentrated solvent-soluble dye containing high conjugate polycyclic compounds in a polyol ester oil system. The product is an amber colored liquid and is completely miscible in most petroleum or organic-based products such as POE&PAG. The solvent is used in the product as a viscosity depressant and standardizing agent. Fluorescent Oil Dye SL3600 applies to POE/PAG lubricant, mineral oil lubricant, and is also available for systems using Poly Vinyl Ether (PVE) lubricant.

Typical Uses:
Fluorescent Oil dye SL3600 can be used for leak detection in air conditioning systems. Applications include HVAC/R and Automobile air conditioning. This application requires the addition of the fluorescent dye to the compressor oil or the refrigerant and subsequent examination of the A/C system using a high-intensity black light. Leaks are easily detected with this system by the intense bright yellow-green fluorescence of the dye. This fluorescence is readily distinguished from the natural blue fluorescence found in some oils.
Application Recommendations:
Introduction of the dye into the system can be carried out in one of two ways. Dye may be premixed with A/C compressor oil or refrigerant and added to the A/C system before the test, or use a specific injector to add fluorescent dye while the system is off or running.
Leakage is monitored during and after the test by examining the A/C system with a high-intensity black light. Leakage is readily detected by the presence of a bright yellow-green fluorescence caused by the presence of the dye.
Fluorescent Oil dye SL3600 can remain safely in the system without harmful effects on the A/C system. This makes it fast and easy to pinpoint leaks, confirm repairs, and perform future preventive maintenance checks.
Recommended Dosage:
The following recommendations are provided as a starting point for typical applications. Actual dosage will depend on desired color strength as well as the background color of the base material.
Refrigerant(R134a/R-1234yf) 3%
Synthetic lubricant 2%
Mineral lubricant 2.5%
Clean Up:
The dye is easily removed from metal surfaces with a common cleaner or by dry wiping.
Storage:
As a non-dangerous product, this product can be transported and stored as a common chemical. The recommended storage temperature for this material is between -10 and 40°C. Exposure to excessively low temperatures should be avoided, as it may cause increased levels of precipitation. This product should be sealed in a cool, dry place away from light.
If product containers are kept sealed in a dry place away from light and extreme temperatures are avoided, the shelf life of the material is greater than 3 years. The container should be tightly closed when not in use to prevent solvent evaporation.
